Trinity Seven is a fantasy romantic comedy manga series by Kenji Saitō with art by Akinari Nao that has been collected into eighteen tankōbon volumes. It began serialization in Monthly Dragon Age in 2010. Yen Press publishes the manga in English and describes it as:

Arata Kasuga transfers to the Royal Biblia Academy to solve the mystery of the destruction that is ravaging the world and that – more importantly – has stolen his cousin Hijiri from him. It’s a tough road that lies ahead of Arata, but nothing’s impossible when you have seven beautiful girls – each a master of her own magical art – at your side!

A twelve episode anime adaption of the manga by Seven Arcs Pictures aired between October 2014 and December 2014. The first anime film, Trinity Seven the Movie: The Eternal Library and the Alchemist Girl premiered on February 25, 2017.
